Sympy and PhysicalQuantities

>>> from sympy import *
>>> init_printing()
>>> a = 1 m * Matrix([ [1,2,3], [4,5,6]])
>>> b = 1 cm * Matrix([ [1,2,3], [4,5,6]])
>>> a

\(\left[\begin{matrix}1 & 2 & 3\\4 & 5 & 6\end{matrix}\right] \text{m}\)

>>> a+b

\(\left[\begin{matrix}1.01 & 2.02 & 3.03\\4.04 & 5.05 & 6.06\end{matrix}\right] \text{m}\)

>>> x = Symbol('x')
>>> 1 m * x

\(x \text{ m}\)

>>> a = 2 m * x
>>> a

\(2 x \text{ m}\)

>>> a/3

\(\frac{2 x}{3} \text{m}\)

>>> Integral(sqrt(1/x), x)

\(\int \sqrt{\frac{1}{x}}\, dx\)
